It may sound unbelievable, especially for this close to April 1, but it is true.

A small dog from Killeen, Texas, dug a hole under a fence in his backyard and turned up at an animal shelter in Hamilton, Ohio, four days later.

The owner of the dog and the shelter have no idea how the dog made it all the way to Hamilton, which according to Google Maps is more 1,100 miles away or roughly a 16-and-a-half-hour drive.

However, the dog, whose name is Corbin, is on his way back to Texas and was expected to be reunited with his family sometime Wednesday evening.

"It sounds like one of those too good to be true stories," said Mike Saiz, who owns the dog. "This isn't the first time he dug a hole under the fence. One time he was waiting for us on our front porch and the other two times we had to pick him up from the local pound."

After digging that hole March 25, Corbin was left outside the Animal Friends Humane Society shelter on Friday evening.

The shelter's staff found the dog Saturday, tied up to a bench and soaking wet from being left out in the rain.

After bringing Corbin indoors, the staff scanned him for a microchip and called the owners, who they assumed moved to Ohio from Texas but didn't update their information, Saiz said.

"They called my wife and she told me that they found our dog, but she didn't sound happy about it," Saiz said. "I asked if he was OK and she told me he was fine. I then asked where the shelter was and she said, 'Hamilton - not Hamilton, Texas, but Hamilton, Ohio."

KCEN, a television station based in Eddy, Texas, heard about the story and shared it on its Facebook page.

After the Facebook post, Saiz said he was offered help from all over the country and eventually came into contact with a woman who lives Killeen and was in Springfield, Ohio, for her mother's funeral.

Corbin is currently with the woman en route back to his home.

"The outpouring show of support is unbelievable. So many people were willing to help," Saiz said. "We are just amazed about the whole situation and that he is heading home right now."

Meg Stephenson, executive director of Animal Friends Humane Society, said there was no way for the shelter to find the dog's family without the microchip.

"When you leave an animal outside the shelter, not only are you exposing it to the elements it is also likely a missed opportunity to ID it," Stephenson said. "It was amazing to find the microchip. Without we would have never known."

The shelter released surveillance images of the person who dropped off Corbin. Stephenson said the Butler County Sheriff's Office, dog warden division, is hoping to identify the woman to find out how the dog made it all the way to Hamilton. The dog warden division can be reached at 513-785-6542.

Stephenson also wanted to encourage pet owners to get a microchip for their animals. She said that the Animal Friends Humane Society offers microchipping seven days a week without appointment for $20.
